WSO2 和创建可部署存档从 Maven 获取旧属性

Question

我对 WSO2 ESB 有另一个问题。我创建了一些 Maven 项目。该项目包含在 WSO2 的 Java 库项目中。在库项目中，我在 pom.xml 中设置了 maven-bundle-plugin 集。它通过 Maven 构建正确创建 MANIFEST，但 Export Project as Deployable Archive 使用旧属性创建 MANIFEST.md（我认为，通过 Eclipse 创建新项目后带有属性的 MANIFEST（未更改 SymbolicName，无导入）。

带有捆绑 POM.xml 的类的 Maven 项目

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
  <modelVersion>4.0.0</modelVersion>

  <groupId>com.coig.esb.osgi</groupId>
  <artifactId>emf</artifactId>
  <version>1.0.0</version>
  <packaging>jar</packaging>

  <name>emf</name>
  <url>http://maven.apache.org</url>

  <properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
  </properties>

  <dependencies>
    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <version>3.8.1</version>
      <scope>test</scope>
    </dependency>

    <!-- https://mvnrepository.com/artifact/javax.persistence/javax.persistence-api -->
  <dependency>
      <groupId>javax.persistence</groupId>
      <artifactId>javax.persistence-api</artifactId>
      <version>2.2</version>
  </dependency>

  </dependencies>
</project>

然后将上面项目中的 jar 文件从 WSO2 导入到 Java 库项目中。

当我创建了Mediator项目，设置maven-bunlde-plugin来导入我之前提到的模块，也有同样的情况。 Maven 构建会创建正确的 MANIFEST.md，但将项目导出为可部署存档会创建属性未更改的 MANIFEST.md。

您能否提供一些意见，应该如何设置？

Answer 1

看起来“将项目导出为可部署存档”不支持 MANIFEST.MF 中的 Import-Package 标头。此文件由忽略此标头的MediatorExportHandler 类构建。

IJavaProject javaProject = JavaCore.create(project);

List<String> exportPac =getExportPackages(javaProject);
BundleManifest manifest = new BundleManifest();    
manifest.setBundleName(project.getName());
manifest.setBundleSymbolicName(project.getName());
manifest.setBundleDescription(project.getName());
manifest.setBundleVersion("2.0");
manifest.setExportPackagesList(exportPac);
[...]
File manifestFile=new File(metainfPath,"MANIFEST.MF");
FileUtils.createFile(manifestFile, manifest.toString());
